Traffic noise and cardiovascular risk: the Caerphilly and Speedwell studies, third phase--10-year follow up

Arch Environ Health. 1999 May-Jun;54(3):210-6. doi: 10.1080/00039899909602261.


The authors tested the hypothesis that prolonged exposure to road traffic noise causes ischemic heart disease in a 10-y follow-up cohort study of middle-aged men. In the Caerphilly and Speedwell studies, 2512 and 2348 men, respectively, who were 45-59 y of age were seen in the initial cross-sectional phase and at follow-up intervals of 10 y. Adjusted odds ratios of 1.1 (95% confidence interval = 0.6, 1.9) and 0.9 (95% confidence interval = 0.6, 1.4) were found in the total cohorts. However, the relative risk was 1.3 (95% confidence interval = 0.8, 2.2) in the pooled reconstructed cohort of men who were followed for 6 y (i.e., from phase 2 to phase 3) and for whom room orientation and window-opening habits could be considered. Furthermore, the relative risk increased to 1.6 (95% confidence interval = 0.9, 3.0) in the subsample of men who had lived at least 15 y in their present homes at the time of recruitment. Living adjacent to streets with high traffic noise levels was associated with an adjusted (for covariates) increase in relative risk of 1.01-1.02/y in residence--a result that was only borderline significant (p < .10).
